Velux case study

The Need

VELUX runs an extensive business that relies on seamless communication and collaboration among its 100 locations around the world. Ensuring it has high-quality communication infrastructure is critical for the company, as it has built a reputation for providing excellent customer care from its 25 international contact centers.

Consolidating voice providers

Going from 30 to 1

Complex vendor management

Replaced over 60 of its own local gateways with six Global Session Border Controllers hosted in three different regions in the Microsoft Azure cloud

The most
inspiring feature

The company needed to enable telephony from the Teams app to ensure a full unified communications capability for its staff and customer service teams.

We looked closely at the cost and business case for achieving our goal of moving everything to the cloud. We found that using Microsoft Teams and working with GTT to enable voice for our new, completely cloud-based solution would bring us a great many benefits.

The GTT Solution

Improving global collaboration and productivity

GTT’s SIP Trunking service with its extensive global reach enables a fast and easy integration of VELUX critical business communication over Microsoft Teams to improve global collaboration and productivity. GTT delivers local telephone numbers to VELUX users across the globe. Outbound calling costs can be easily managed with the simple pricing structure, and overall spend is reduced, as site-to-site calling is free of charge with GTT.

VELUX took advantage of the ability to run GTT SIP Trunks in parallel with its existing services. This enabled VELUX to start building out its new SIP Trunk and run a pilot. Learning from and documenting its experiences, VELUX was able to apply them in an agile way to its comprehensive global user audit and match exact requirements across its offices.

VELUX has moved to a new setup with six software-based Session Border Controllers in three Microsoft Azure cloud hubs in North America, Europe and Asia. Each SBC is delivered with a fully resilient SIP Trunk service from GTT. In addition, GTT delivers Dedicated Internet Access to a dozen VELUX sites across Europe, North America and Australia.
